10 Unforgiving Video Games Hardly Anyone Can Beat

On the face of things, there's not a whole lot in play when it comes to Rock Band 2 being a video game that anyone is likely to have difficulty completing.

But, whilst the game certainly has some songs that can prove a worthy adversary to fully perfect, anyone hoping to fully complete the game will soon encounter a challenge that pushes things to absolute physical limit (literally).

In order to get every achievement in the game, players will have to pick up the infamous 'Bladder of Steel' trophy.

In what is honestly one of the few video game achievements that prioritise a player's physical performance on the other side of the screen, the Bladder of Steel achievement requires players to complete the Endless Setlist 2 without pausing or failing once. The setlist can take a whopping six hours to complete, with the game only giving players a handful of opportunities to pause for a break.

In total, there are 84 songs to complete when it comes to the endless setlist on Rock Band 2, with less than 4% of players ever managing to complete this gruelling challenge.
